“Look where you are going! Never mind de talking till we get down,” put in Peter Anderledy.

The peremptoriness of the rebuke brought Phil’s head back from over his shoulder with the celerity of a recruit at the word “eyes right!” Then he growled. But this expression of his dissatisfaction made upon the stolid guide not the faintest impression.

Herr Gott!” imprecated the latter presently, with set teeth and a savage glance upward as he stopped to listen. “De shtones are falling.”

High above among the cliffs, but slightly in front of their line of march, a hollow rattle became audible. There was something weird and uncanny about the sound. No mortal hand, no mortal agency had loosened those rocks and sent them hurtling down into the depths below. It was almost as if the demons of the air were abroad.

The party was descending a long couloir or gully, which traversed obliquely the iron face of the mountain. The crannies of the rocks were filled with snow and the footing was good. Here and there a bit of sloping ice necessitated the cutting of a step or two, but, on the whole, the way was easy. Yet the guides seem to cast anxious glances upward, and ever and anon that ghostly echoing rattle was heard.

“Sunshine is a delightful thing,” quoth Fordham. “But like everything else to which that term applies it is bound to have its obverse side. I could wish just now it had been cloudier and colder.”

“Why the deuce should you wish that?” said Philip.

“Because then there wouldn’t be so many stones flying. You see, they’re frozen to the rock by a thin cementing of ice. As soon as the sun has any power that ice melts and they slide off. All these rock mountains are the very devil for falling stones. On the Matterhorn you hear them rattling all day long—”

A vehement imprecation from both guides simultaneously, interrupted them. There was a rushing sound in the air very like the “whigge” of a shell, and a shadow seemed to swoop over their heads. Looking upward they beheld a solid mass of rock of at least two tons’ weight, sailing through the air. It had shot outward from the last projecting portion of the cliff upon which it had struck, and now describing a lofty arc it whizzed directly over their position, and striking the rocks some hundred feet lower split into fragments, which went crashing and roaring down to the glacier beneath.

Fordham, contemplating this occurrence, shook his head slightly and said nothing. Philip opened his eyes wide and ejaculated, “By Jove!” The guides swore with renewed energy. Each action was characteristic.
